I'm healthy at the moment and I'm still not sure I understand. Poetic perhaps, but a bit nonsensical. Old world as in the past? Older technology? Older ideas?

I'm healthy at the moment and I'm still not sure I understand. Poetic perhaps, but a bit nonsensical. Old world as in the past? Older technology? Older ideas? Bad ideas? Blues, as in the musical genre? Or the feeling it conveys? Are we riffing on it here? Plays strongly suggests music, but the blues originated from specific cultural roots tied to the end of slavery (which is implied even further by 'old world blues'). New world, as in a better tomorrow, or something more akin to a new world order? Hope I think I get.
